摘要:
A device for filling or emptying a container (1) containing a liquid particularly intended for consumption has a rod (5) arranged on a holder (4) with a surrounding, balloon-shaped body (6). The length of the rod (5) can be adapted to different distances between the top opening (3) of the container (1) and the base (2) of the container (1).
摘要:
A container (1) for storing a liquid foodstuff (4) and dispensing it under pressure in consumption portions via a closable dispensing channel, characterized in that it comprises a rigid outer container (2), a flexible inner container (3) for the foodstuff (4), and at least one intermediate container (5) surrounding the inner container (3), whereby an intermediate container (5) on the one hand, and another intermediate container (5) or the inner container (3) located within it on the other hand, define a space (16), whereby the space (16) is provided with a pressure medium and/or the container (1) is equipped with a connection (23) connected to the space for a pressure medium source (24).

A dispenser 2 for flowable foodstuffs comprises a rigid shell 6 in which a flexible container 4 for the foodstuff and an inflatable reservoir 12 are received. The container 4 has a connector 16 for attaching a nozzle 20 through which foodstuff is dispensed by inflating the reservoir 12 to apply pressure to displace foodstuff from the container 4. The nozzle 20 is provided with a valve 26 that is operable to open and close the nozzle 20 and is linked to an air compressor for inflating the reservoir 12. Inflation pressure is increased as the foodstuff is dispensed up to a maximum pressure less than the burst strength of the container 4.

A beverage dispenser (10) is disclosed for use with prefilled containers (11) of carbonated beverage. The beverage dispenser (10) incorporates a dispensing valve assembly (21), and is screwed to the neck (13) of the container (11). The beverage dispenser (10) also contains a supply of carbon dioxide (23) for pressurizing the container (11) and for replacing beverage withdrawn from the container (11). This allows a quantity of beverage to be withdrawn from the container (11) without loss of carbonation of the remaining liquid, and without contamination of the remaining liquid by air.
摘要:
Les boissons contenant de l'acide carbonique notamment la biere, doivent etre stockees a l'endroit d'utilisation dans des reservoirs a pression (1) stationnaires. Le reemplissage des reservoirs (1) avec la boisson doit etre fait par camion-citerne (23). La boisson est introduite dans le reservoir (1) avec un gaz de pression, notamment avec du bioxyde de carbone. Les reservoirs (1) contiennent une doublure (40), qui empeche le liquide d'entrer en contact avec la paroi. Une source de gaz (30) stationnaire est a disposition a l'endroit d'utilisation, pour puiser la boisson hors du reservoir. Lorsque toute la boisson a ete enlevee d'un reservoir (1), celui-ci ne contient plus que du gaz de pression. Lorsque le reservoir vide doit de nouveau etre rempli avec la boisson, le gaz de pression doit etre elimine du reservoir (1). Etant donne que le gaz de pression, notamment le bioxyde de carbone, est normalement plus lourd que l'air, on ne peut sans autre le laisser echapper dans l'entrepot ou se trouve les reservoirs (1), sans creer un danger pour les personnes penetrant dans cet entrepot. Pour cette raison, les camions-citerne (23) doivent etre equipes d'une pompe a gaz de pression (46) et d'un reservoir de gaz de pression (47), permettant ainsi la recuperation du gaz de pression hors des reservoirs avant ou pendant le remplissage avec la nouvelle boisson. De plus, les camions-citerne (23) doivent etre equipes d'une installation de "recyclage" permettant de regenerer le gaz de pression recupere (48) et ainsi pouvoir reemployer ce gaz.
摘要:
A method for emptying a container (1) filled with liquid (7) has a balloon-like body (6), which is introduced into the container (1). Expansion medium (8) is introduced into this balloon-like body (6), and so the balloon-like body (6) is inflated and the liquid (7) is forced out of the container (1).
摘要:
Briefly, this invention uses one or more pressure vessels having installed therein on its inside a balloon of flexible and non-expandable wall to smoothly and continuously deliver a chemical to any end user without contamination and gas dissolution. Since the balloon installed inside the pressure vessel isolates a high pressure gas from the chemicals, gas dissolution in the chemical and the resulted gas bubble problems are effectively eliminated. Further, contaminants in the high pressure gas which fills the balloon will not be transferred into the chemical and the extremely toxic chemical will not be transferred into the gas to be exhausted as a serious environmental issue. Unlike the vacuum/pressure system, the contamination by the ambient air leaking into the system is avoided because the disclosed delivery system is always with the pressure higher or equal to the ambient pressure.
